# FBX Viewer

> An FBX viewer is a tool that opens Autodesk's .fbx scene format without Maya, 3ds Max or a game engine. Kenerate's free FBX viewer runs in your browser with three.js: see the model with embedded textures, switch to clay or wireframe, and read its triangle and mesh counts. It shows the rest pose; nothing is uploaded.

## Key facts
- Price: Free, no account
- Opens: FBX binary and ASCII (version 7.x), plus STL, OBJ, GLB, 3MF, PLY
- Shows: Embedded textures (not external texture paths), in rest pose — animations aren't played or exported
- Views: Textured · Clay · Wire · Normals
- Save as: GLB, OBJ, STL, 3MF, PLY, USDZ
- Privacy: Parsed locally — no upload
- Game assets, checked fast: See a prop or character's shape, texture and polycount before you import it into Unity or Unreal.
- Mesh first: Clay and wireframe show the real geometry under the texture — handy for judging AI-made or marketplace assets.
- Embedded textures: Textures packed inside the FBX are applied. Files that point at textures in another folder open untextured.
- Polycount: Triangle, vertex and mesh counts tell you if an asset suits mobile, web or PC budgets.
- Open format out: Save as GLB for the web and most engines, or OBJ for older tools.
- Any computer: Works on Mac, Windows, Linux and Chromebook in a modern browser.
- Read: The binary or ASCII FBX is read into memory.
- Parse the scene: Meshes, materials, embedded textures and the node hierarchy are rebuilt.
- Rest pose: The model is shown in its bind pose, centred and scaled to fit the view.
- Inspect: Orbit, change shading, read the stats or save to an open format.
- FBX (Filmbox): Proprietary scene format; by Autodesk, 1996 (Kaydara). Holds: Meshes and materials, Skeletons, skinning and animation, Cameras and lights. Lacks: An open specification. Best for: Game engines and animation pipelines. Opens in: Unity, Unreal Engine, Maya, 3ds Max, Blender.
- GLB (glTF 2.0 Binary): Single-file scene with PBR materials; by Khronos Group, 2017 (glTF 2.0). Holds: Meshes and PBR materials, Textures in the same file, Animation and skins. Lacks: Units beyond metres, CAD precision. Best for: Web, AR and real-time apps — the “JPEG of 3D”. Opens in: Browsers (three.js, model-viewer), Blender, Unity, Unreal, Godot.
- OBJ (Wavefront OBJ): Plain-text mesh; by Wavefront Technologies, 1980s. Holds: Vertices, faces, UVs and normals, Materials via a separate .mtl file. Lacks: Animation and rigs, Embedded textures. Best for: Moving static meshes between 3D apps. Opens in: Blender, Maya, 3ds Max, ZBrush, most slicers.

## Steps
1. Open the FBX — Drop the .fbx onto the box above or click to choose it. Or try the sample chest made with Rodin.
2. Orbit around it — Drag to rotate, scroll or pinch to zoom, right-drag to pan.
3. Inspect — Switch to Clay or Wire and check the polycount.
4. Convert if needed — Pick GLB, OBJ or STL and download.

## In depth

### Where FBX came from
FBX began as Filmbox, motion-capture software by Kaydara, in 1996; Autodesk bought it in 2006 [3]. It became the standard exchange format for game and film pipelines because it carries meshes, materials, skeletons, skinning, animation, cameras and lights in one file [3].

### The catch: a closed format
FBX has no public specification; tools outside Autodesk rely on its SDK or on reverse-engineered readers [3]. That's why FBX files can open differently in different apps, and why open formats like glTF are often preferred for delivery [4].

### FBX vs GLB for game assets
Both carry meshes, materials, rigs and animation. GLB is open, compact and web-ready; FBX is better supported by older DCC tools and some engine import pipelines. Unity, Unreal and Godot import both.

## FAQ
Q: Is the FBX viewer free?
A: Yes, free with no account. It runs entirely in your browser.

Q: Do I need Autodesk software?
A: No. The file is read by an open-source FBX loader in the page.

Q: Why are my textures missing?
A: Many FBX files reference textures stored next to them rather than inside. A single uploaded file can't include those, so the model shows untextured. Re-export with “Embed Media” turned on.

Q: Does it play animations?
A: No — the model is shown in its rest pose, and exports contain the static mesh.

Q: Which FBX versions open?
A: Binary and ASCII FBX version 7.x, which covers files from roughly the last decade. Very old 6.x files may fail.

Q: Can I convert FBX to OBJ or GLB?
A: Yes. Pick the format and download. GLB keeps textures as PBR materials; OBJ and STL keep the geometry.

Q: Is my file uploaded?
A: No. It never leaves your device.

Q: Can Blender open FBX files?
A: Yes. Blender imports FBX with File → Import → FBX (.fbx), including meshes, materials, armatures and animation. Textures that aren't embedded must sit next to the file. To check an asset before importing, open it in this viewer first and look at its polycount.
